It should be noted that the various information may be directly sent to the vehicle-mounted software upgrading system, or may be sent to another information processing device first, and then the information processing device sends the processed information to the vehicle-mounted software upgrading system after corresponding information processing.
In the present embodiment, the wireless communication module 3 is an Electronic Control Unit (ECU) integrated with an extranet communication function, such as a T-Box, of the vehicle. The software reading device 1 may be an ECU of a vehicle, which has a function of reading upgrade software of on-board software from an external device, and the ECU may read corresponding upgrade software from the external device through a USB interface, an OBD diagnostic interface, or the like. The onboard software may be electronic control unit software (i.e., ECU software) of the vehicle, or may also be gateway driver software, etc., and is not limited herein.
The vehicle-mounted software upgrading method provided by the embodiment of the invention comprises the following steps:
and S10, obtaining the upgrade software read by the vehicle from the external equipment at present, and verifying the upgrade software according to a preset software verification algorithm to generate a software verification value.
In the present embodiment, the external device is, for example, a USB storage device (e.g., a USB disk); the preset software checking algorithm is a CRC algorithm, and may also be other algorithms that can calculate a software check value, and is not specifically limited herein.

After the step S500, the method may further include a step S502 of:
and S502, if not, terminating upgrading of the corresponding vehicle-mounted software of the vehicle.
In this embodiment, if the diagnosis result of the gateway is that the upgrade software is not complete, it indicates that the upgrade software is correct but incomplete, so that the upgrade of the corresponding vehicle-mounted software of the vehicle is terminated.
In any of the above embodiments, specifically, the sending, in response to the received upgrade negative instruction sent by the server after the matching of the software verification value fails and the matching of the software version number succeeds, an upgrade software delivery request to the server, so that the server delivers, according to the upgrade software delivery request, upgrade software that is pre-stored and corresponds to the software version number includes steps S400 to S401:
s400, responding to a received upgrade negative instruction which is sent by the server after the software verification value is unsuccessfully matched and the software version number is successfully matched, and controlling a display device of the vehicle to display whether the upgrade software downloads an operation option or not so as to be selected by a user.
Specifically, when the server fails to match the software verification value and successfully matches the software version number, it indicates that the upgrade software currently read by the vehicle is unsafe, and indicates that the upgrade software corresponding to the software version number is pre-stored in the server, at this time, the server sends a negative upgrade instruction to the gateway, and the gateway responds to the negative upgrade instruction received, and controls a display device of the vehicle to display whether the upgrade software downloads an operation option for a user to select. In addition, the gateway can also control a display device of the vehicle to display content information such as upgrade failure and the like so as to prompt a user that the upgrade software read by the vehicle currently is unsafe.
S401, responding to the operation that the user selects the upgrade software to download, and sending an upgrade software issuing request to the server, so that the server issues the upgrade software which is pre-stored and corresponds to the software version number according to the upgrade software issuing request.
Specifically, if the user selects the downloading operation, the gateway responds to the operation and sends an upgrade software issuing request to the server. And after receiving the request, the server searches whether the upgrading software corresponding to the software version number exists in the server according to the software version number, if the upgrading software corresponding to the software version number is stored in the server in advance, the server is requested to issue the prestored upgrading software corresponding to the software version number, and the gateway can continuously upgrade the vehicle-mounted software corresponding to the vehicle according to the received upgrading software. In addition, after the upgrade is completed, the gateway can send the instruction of successful upgrade to the display device of the vehicle-mounted software upgrade system, and control the display device to display the successful upgrade so as to inform the user.
After the step S400, the method may further include a step S402 of:
s402, responding to the operation that the user selects not to download the upgrading software, and terminating the upgrading of the corresponding vehicle-mounted software of the vehicle.
Specifically, if the user chooses not to download the upgrade software in the server, the gateway 2 controls the vehicle-mounted software to terminate the upgrade.
